Comparative database metrics for different implementations of Django Model
Considering two approaches in designing Django models: 1 - Very few models, but each model has a long list of fields. 2 - Many models, each model has significantly shorter list of fields. But the models employ multi-level hierarchical one-to-many structure. Suppose they both use Postgres as the database. In general, what would be the comparative database size, latency in retrieving, processing and updating data for these two approaches? -

Django - serving static files from collect_static folder in dev
I'm having troubles figuring out how I can serve my static files from the folder where I collect all static files (for eventually in production have those served from a different server). My frontend static files are under projectroot/frontend, and the static files folder where they collect is undert projectroot/static My settings.py files looks like this for the relevant bits: STATICFILES_DIRS = [ os.path.join(BASE_DIR,'frontend'), ] STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') MEDIA_URL = "/media/" MEDIA_ROOT = os.path.join(BASE_DIR, "media") Then my urls.py (the root confs) look like this: urlpatterns = [ path(.....), ] urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) Then I run the dev server using python manager.py runserver. If I run python manage.py collectstatic, then I indeed see all the relevent files collected under projectroot/static. However, if I remove/rename the original folder (/frontend), then the static files are not served by the dev server, meaning it isn't using the /static folder. Which I would prefer to use even in dev, just because I'd rather catch any random issue right away.... What am I doing wrong? -

Update data from view context on post
I'm trying to update the context that i send to a template after receiving a post. Example of what i want to update in a template : <div id="testbox"> <a id="test ok">test</a> {{ element }} </div> The ajax for the post and update of the div : $(document).on('click', '#test', function (e) { e.preventDefault(); elementname = this.id; const request = new Request( "", {headers: {'X-CSRFToken': csrftoken, 'Content-Type': 'application/json'}} ); fetch(request, { method: 'POST', body: JSON.stringify({ pluginEdit: elementname }), mode: 'same-origin' }).then(function() { $('#testbox').load(document.URL + ' #testbox'); }); }) Extract of my views.py : if body.get("pluginEdit"): context = { //some things i send anyway 'element': body.get("pluginEdit") } return render(request, 'myapp/dashboard.html', context) I tested if it enters my "if" even though the page is already loaded, which it does, but the new part of the context doesn't reach the template when it's updated with js. Didn't found any other to do that by the way, so what am i doing wrong ? -

However, I am struggling to access the contents of the .csv form file. The code in the view looks like this if request.method == "POST": form = SmsWebForm(data=request.POST, files=request.FILES) if form.is_valid(): phone_num = form.cleaned_data["phone_number"] csv_num_file = form.cleaned_data['csv_file'] orig_text = form.cleaned_data['text'] number_format = form.cleaned_data["number_format"] if not csv_num_file and not phone_num or phone_num and csv_num_file: raise forms.ValidationError("Právě jedno z polí 'telefonní číslo' nebo 'csv soubor' musí být vyplněno") if csv_num_file: with open(csv_num_file.seek(0), "r", encoding="utf-8") as f: csv_num_file.close() reader = csv.DictReader(f) for row in reader: print(row) for number in reader: ...

How can I add a Bootstrap modal that contains a model form into another Django model form?
I have a model form "NewJobEntryForm" which creates a new JobEntry, and in that JobEntry form, users can select ServiceItemStats objects that will be associated by a many-to-many relationship. I would like to enable the user to create new ServiceItemStats objects if they need to, without leaving the JobEntry form. For this, I would like to use a Bootstrap modal that would hold a "NewServiceItemStatsForm", but I am not sure how to go about doing this. Any help would be appreciated. My code is: Models.py class JobEntry(models.Model): # PK: id - automatically assigned by Django. job_entry_date_time = models.DateTimeField(default=timezone.now) job_date = models.DateField(blank=True, null=True) job_checked_in = models.BooleanField() job_checked_out = models.BooleanField(default=False) job_priority = models.IntegerField() job_time_estimation = models.IntegerField(blank=True, null=True) job_comments = models.TextField(max_length=200, blank=True, null=True) job_parts_instock = models.BooleanField(default=False) job_started = models.BooleanField(default=False) job_finished = models.BooleanField(default=False) vehicle = models.ForeignKey(Vehicle, on_delete=models.CASCADE) #One-to-one relationship customer = models.ForeignKey(Customer, on_delete=models.CASCADE) #One-to-one relationship serviceBay = models.ForeignKey(ServiceBay, on_delete=models.CASCADE, blank=True, null=True) #One-to-one relationship serviceItemStats = models.ManyToManyField(ServiceItemStats, blank=True) #Many-to-many relationship class ServiceItemStats(models.Model): service_stats_name = models.CharField(primary_key=True, max_length=20) service_stats_estimate_duration = models.IntegerField() # Many-to-many relationship with JobEntry. def __str__(self): return self.service_stats_name Forms.py class NewJobEntryForm(ModelForm): class Meta: model = JobEntry fields = ['vehicle', 'customer', 'job_date', 'job_checked_in', 'job_priority', 'job_comments', 'job_parts_instock', 'serviceItemStats'] widgets = { 'job_date' : forms.DateInput(format=('%m/%d/%Y'), attrs={'class':'form-control', 'placeholder':'Select a … -
Passing an Object into Include Template Tag Django
I am developing a website in django and I have encountered a problem. I am using an 'include' template tag and I am trying to pass an object into the tag. But whenever I pass it in, it is passing in the dunder str method of the object. {% include 'function/comment' object=answer %} 'answer' is the object I want to pass in (fyi it is a model object) Instead of passing 'answer' as an object it is passing the dunder str method. Is there a way to solve this? Thanks in advance.
